In this case the By means of two substantially U-shaped links frame of the vehicle is constructed as shown in which may swing in a horizontal plane and are Fig. 6 and at each side terminates in aforked driving aggregate to the rest of the vehicle. y ends of the frame a, a supporting member d is of the rubber sleeves u also are connected by vulcanization to the interior walls of the openings in the forked ends of the frame of the vehicle. In this manner the entire axle aggregate is rendered laterally displaceably. For the sake of clearness the axle aggregate has been omitted in Fig. and in Fig. 6 the frame only is shown to clearly illustrate the connection of the supporting frame to the frame of the vehicle.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed we declare that what we claim is: l

1. In a vehicle having a main frame, a subsidiary substantially rectangular frame, including upper and lower transverse tubular sections, positioned in a substantially vertical transverse plane, means yieldably connecting said subsidiary frame to said main frame for movement transversely of said main frame, and a vehicle driving unit, including drive gears and driven wheels, connected to and movable with said subsidiary frame. 2. In a vehicle having a main frame, a subsidiary substantially rectangular frame positioned in a substantially vertical transverse plane, means yieldably connecting the opposite outer sides of said subsidiary frame to said main frame for movement transversely of said main frame, and a vehicle driving unit, including drive gears and driven wheels, connected to and movable with said subsidiary frame. v

3. The combination according to claim 2,- in which said driving unit includes the vehicle engine.

4. The combination according to claim 2, in which said driving unit includes the vehicle engine and the speed-change gear, the engine being connected to said subsidiary frame at its forward end and extending rearwardly thereof, the drive gears being positioned forwardly of said subsidiary frame, and the change speed gears forwardly of said drive gears.

5. The combination according to claim 2, in which the means connecting the subsidiary framev to the main frame includes rubber bushings.

6. 7I'he combination according to claim 2, in combination with swinging half-axles supporting said wheels on said driving unit, and spring of links, each link having the form of an inverted U, means pivotally mounting the legs' of said links in said pivot block with the tops of said links extending in a generally longitudinal direction, so that said links form a parallelogram with said main frame and driving unit, whereby said main frame and driving unit can move relatively to one another transversely of said vehicle; and means in at least some of said pivot blocks, intermediate the latter and the respective link'legs for yieldably vresisting pivotal movement of said legs in said pivot blocks and thereby resisting relative transverse motion of said main frame and driving unit.

9. 'I'he combination according to claim 8, in which said yieldable means comprises a hollow rubber bushing in said pivot blocks attached on the outside to said pivot blocks and on the inside to the legs of said links.

10. In a vehicle having a main frame, a subsidiary substantially rectangular frame positioned in a substantially vertical transverse plane and including a vertical hollow tubular member on each side of the subsidiary frame, a pair of links having a substantially longitudinally directed portion pivotally connected about a vertical axis to the main frame at one end and havy ing a depending leg on its other end pivotally means intermediate said swinging half-axle and mounted in one of the vertical tubular member of the subsidiary frame, whereby said links form a parallelogram with said main and subsidiary frames so that said frames can swing transversely of one another, means for yieldably resisting said transverse swinging, and a driving unit for said vehicle including drive and driven wheels, attached to said subsidiary frame.

l 11. The combination according to claim l0, in which said yieldable means comprises hollow rubber bushings attached on the outside within said vertical tubular members and on the inside to the depending legs of said links.

12. The combination according to claim 10, in

which said subsidiary frame includes hollow transverse tubular sections interconnecting said vertical tubular members.

13. The combination according to claim 10, in which said driving unit includes the vehicle engme.

14. 'I'he combination according to claim 1, in which said subsidiary frame includes vertical tubular members interconnecting the outer ends of said transverse tubular members.

15. The combination according to claim 10, in which said subsidiary t'rame includes a pair of transverse sheet metal plates attached face to face and extending between said vertical tubular members, said sheets being formed with cooperating substantially semi-circular oppositely positioned troughs along their upper and lower edges forming together hollow transverse tubular strengthening beams.

16. T-he combination according to claim 1, in which said main frame is formed with a pair of vertical forked rearward extensions, and said yieldable means comprise rubber bushings mounted in said forks and about the ends of said transverse tubular sections.
